Question 1

What is TDEE?

Accepted Answer

TDEE stands for Total Daily Energy Expenditure. It is the total number of calories your body burns in a day, including your basal metabolic rate, physical activity, and the thermic effect of food. Knowing your TDEE helps you set calorie targets for weight loss, maintenance, or muscle gain.

Question 2

What is BMR?

Accepted Answer

BMR stands for Basal Metabolic Rate. It is the number of calories your body needs to perform basic life-sustaining functions like breathing, circulation, and cell production while at complete rest. BMR typically accounts for 60-75% of your total daily calorie expenditure.

Question 3

What is the Mifflin-St Jeor equation?

Accepted Answer

The Mifflin-St Jeor equation is considered the most accurate formula for estimating BMR. For men: BMR = (10 x weight in kg) + (6.25 x height in cm) - (5 x age in years) + 5. For women: BMR = (10 x weight in kg) + (6.25 x height in cm) - (5 x age in years) - 161. This BMR is then multiplied by an activity factor to estimate TDEE.

Question 4

How accurate are TDEE calculators?

Accepted Answer

TDEE calculators provide a reasonable estimate, typically within 10% of your actual expenditure. Accuracy depends on how honestly you assess your activity level and body composition. For best results, use the calculated TDEE as a starting point, then adjust based on real-world results over 2-4 weeks.
